This is most likely a harmless Zygiella species, probaby Z. x-notata, one of the missing sector orb weavers. Very common in & around houses & buildings.

As you can see the head is light brown around the sides, with a thick, dark central stripe. Steatodas (false widows) tend to have a more uniform colouring accross the whole of the head. Also note that on the abdomen, there is a fine, dark line, running down the centre of the markings, this is not typical of false widows. Lastly, the spider in the photo has very clear stripes around the legs, adult male false widows & adult females tend to have more uniform colouring on the legs, though sub-adult steatoda nobilis can have some striping.
